these needed a bit of balancing I needed to make an adaptor to fit the props on my balancer then they worked fine.Great props. The finish was slightly rough, but came pretty well balanced and work great. I'll be ordering more in the future.Good propellers, quite well made and balanced, but I am not satisfied with the quality service. I ordered 2 pairs and one off them was mixed with a 11" propeller. I am very disappointed...
